how to get nrf5340 soc temperature

[tianwanjie]

Can I get the temperature of the nrf5340 SOC via sd_temp_get just like nrf52 ?

[tianwanjie]

thanks,i solve it.  by the way, can i call nrfx_temp_measure() function directly from appCore?

I got some more insight into this.

In NCS v1.5.0, there was added an HCI command for reading the temperature:

• SDC_HCI_OPCODE_CMD_VS_ZEPHYR_READ_CHIP_TEMP
  • Triggers sdc_hci_cmd_vs_zephyr_read_chip_temp() 
• changelog NCS v1.5.0

You can also use the function mpsl_temperature_get() (this was replaced by the function ble_controller_temp_get())

hello,simon 

After I have tested nrfx_temp_measure, I can normally read the temperature data, but some of the devices in my hand will have the phenomenon that the read temperature is 0. After I reset it by NVIC_SystemReset function, the read value of nrfx_temp_measure function is still 0.Unable to recover. Do you have any directions?In addition, ask whether the NVIC_SystemReset function can reset netcore?
